Definitions
- New radio transmission protocols and standards are continually being developed to implement advances in radio communication technologies. However, as new devices are developed using new radio transmission protocols and standards, legacy devices using older standards still may exist and be viable for a predetermined lifetime that may overlap with the lifetime of the new devices. As a result, for example in wireless local area network equipment, there may be several devices in deployment that may communicate using a wide array of non-compatible radio transmission standards resulting in a fragmentation of which devices are able to communicate with other devices.
- FIG. 1 is a block diagram of wireless local area network in accordance with one embodiment of the present invention.
- FIG. 2 is a block diagram of an access point having at least one or more configurable radios in accordance with the present invention.
- FIG. 3 is a flow chart of an operation of an access point having at least one or more configurable radios in accordance with the present invention.
- An algorithm is here, and generally, considered to be a self-consistent sequence of acts or operations leading to a desired result. These include physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers or the like. It should be understood, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities.
- Embodiments of the present invention may include apparatuses for performing the operations herein.
- This apparatus may be specially constructed for the desired purposes, or it may comprise a general purpose computing device selectively activated or reconfigured by a program stored in the device.
- a program may be stored on a storage medium, such as, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), electrically programmable read-only memories (EPROMs), electrically erasable and programmable read only memories (EEPROMs), flash memory, magnetic or optical cards, or any other type of media suitable for storing electronic instructions, and capable of being coupled to a system bus for a computing device.
- Coupled may mean that two or more elements are in direct physical or electrical contact.
- coupled may also mean that two or more elements may not be in direct contact with each other, but yet may still cooperate or interact with each other.
- Radio systems intended to be included within the scope of the present invention include, by way of example only, wireless local area networks (WLAN) devices and wireless wide area network (WWAN) devices including wireless network interface devices and network interface cards (NICs), base stations, access points (APs), gateways, bridges, hubs, cellular radiotelephone communication systems, satellite communication systems, two-way radio communication systems, one-way pagers, two-way pagers, personal communication systems (PCS), personal computers (PCs), personal digital assistants (PDAs), and the like, although the scope of the invention is not limited in this respect.
